FIREPLACE-GRATE.

$pecification of Letters Patent No. 4,801, dated October 7, 1846.

To all whom it may concern:

Be it known. that I, JOHN GOLDENBURGH, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and Improved Fire-Grate for Heating Apartments, &c., and that the following is a full, clear, and exact description of the principle or character, which distinguishes my invention from all.other things before known and of the manner' of making, constructing, and using the same, reference being had to the accompanying drawings, making part of this specification, in which Figure l is a front elevation of the grate set; Fig. 2, is a vertical section in a plane parallel with, and taken just behind the front plate.

The same lettersindicate like parts in all the figures.

The nature. of my invention consists in causing the smoke, &c., from a fire grate constructed in the ordinary way, to descend on each side of the said grate in a line parallel with the front thereof, and thence return up and pass out of the chimney, thus heating a broad space on each side of the fire chamber or grate and economizing the fuel,the draft in said fines being regulated by dampers placed just below the return which when open will admit a sufficient quantity of air from the room to the flue, to check the draft of the grate front; (this is clearly. shown in Fig. 2, the grate front being there drawn in red lines) from the end of partition (0) which extends beyond the opening above named on each side two vertical partitions (d, (Z) descend to within a few inches of the dampers at the bottom; these partitions divide the space behind the plate into two flues and cause the products of combustion to descend before they escape; these dampers (e, 6) cover two openings in the grate front, and when raised they admit the air into the fines. The top or horizontal partition (c) has openings in it which can be covered with sliding dampers (f, f); these when they open permit the smoke to pass directly into the chimney, but when closed they turn it down through the side fines.

It will be obvious that the dampers (e, 6) will regulate the strength of draft as well when the smoke passes oif through the openings in partition (0) as when it. is turned down around the side flues, and the great body of the heat is at once carried off, i it is not required. in the apartment.

Having thus fully described my improvement, what I claim therein as new and de sire tosecure by Letters Patent is The combination of the dampers (e, c) with the descending fines behind the front plate and dampers (f, f) connected with the grate, the whole being constructed and arranged substantially in the manner and I for the purpose set forth.

JOHN GOLDENBURGH.
